DHS Equipment supplies this part to help keep your equipment running at full performance. Cross-reference part number 740431200 against your parts diagram to confirm the correct installation point before ordering.
Key Features
- OEM Sealing Specification — Manufactured to Husqvarna's exact elastomer grade and compression tolerance, delivering the same leak-free seal as the factory-installed original.
- Drop-In Replacement Fit — Matches the original groove dimensions exactly, seating cleanly without trimming or modification to the mating surfaces.
- Broad Equipment Compatibility — Fits the DM406 concrete core drill and CS2512 wire saw, covering two distinct Husqvarna Construction equipment families with a single part.
- Fluid and Coolant Containment — Maintains the hydraulic or water circuit integrity these machines depend on, preventing fluid ingress or loss that would compromise drilling or cutting performance.
- Prevents Contamination Risk — A failed or worn O-Ring allows water, slurry, or hydraulic fluid to migrate into sensitive internal components; replacing it promptly protects the surrounding assembly from accelerated wear.
An O-Ring forms a compressed circular seal between two mating surfaces, preventing fluid or air from passing through the joint. In demanding construction equipment like the DM406 core drill and CS2512 wire saw, O-Rings are critical to maintaining coolant flow, hydraulic pressure, and contamination barriers within the machine's internal circuits. When an O-Ring degrades — through heat cycling, chemical exposure, or mechanical wear — it can weep or fail entirely, leading to fluid loss, pressure drop, and potential damage to the components it was protecting.
